This is not a typical error, I can understand your frustration but please understand this does not typically happen. Looking at your log file, it is crashing on GenerateTurnFiles, which leads me to believe it may be a permission denied error on the Saves folder on your machine. What OS are you running on (Windows 8/10?) If its Windows 7,8, or 10, see if you have permissions to create files under Documents->My Games. If not, it is likely the game is crashing when trying to generate the host file for your save.
